SPECIFICATION forming part of Letters Patent No. 20,882, dated July 10, 1883.

Application fllod Apr "0 aZZ whom it may concern.-

Be it knownthat I, Anson C. TIOHENOR, a itizeu of the United States, residing at Alaueda, Alameda county, State of California, :ave made and invented certain new and useul Improvements in Treating Alcoholic Lily ms with Electricity, to purify and impart to hem the character of age; and I do hereby 61818 that the following is a full, clear, and xact description of my said invention, referuce being had to the accompanying drawings.

My invention relates to an improvement in he method or process of treating alcoholic liqlOl'S with electricity to separate and extract hose acrid oils, alcoholic principles, and matcrs of poisonous and deleterious properties which in the ordinary course of treatment are einoved or thrown ofi' by age.

The following description fully explains the lature of my said invention and the manner a which I proceed to apply, use, and carryout he same, reference being had to the accomlauying drawings, in which Figure 1 is a section of the apparatus 1 use,

howing the wireswhich come from the source feleetricity. Fig. 2 is a detail of an electrode, .nd Fig. 3 is the fibrous or textile covering herefor.

A is the vessel to hold the liquor, of ca lacity to hold, say, abarrel of liquor. lcctrieally isolated by being placed on an in ulated base, and a light cover or frame of vire gauze or thin material is placed over it o exclude dust and insects,

An electric generator is provi (led, from which :onductors C 'G are carried to the vessel, where onnection is made to poles or plates 1) l), arming the electrodes.

The best results are obtained by usin tubs 1r vats of about one-barrel capacity and a lynanio-electrie machine having a strength or rowerv equal to.a Daniells battery of forty- *ells. Conductors C G are then led to each eceptacle and connected with a pair of elec rodes in each. Where several receptacles we used in this manner, they should be of ibout uniform capacity.

The-electrodes l) 1) are plates or poles of arbon or metal. Theposit-ive one, D, ismade rue-third larger than-the negatiw one, D.

They are inserted into the liquor at opposilc sides of the tub or receptacle, so that their active surfaces are covered by the liquor, and. the are placed as far apart as the diameter-or size 01' the tub will. admit. The full strength ofthe electric current from the generator is then applied directly through the liquor, and it maintained for a length. of time or number of hours varying with the size and power of the machine, and governed also by thekind oi 60 liquor being treated.

This process or operation is substantially the same both in treating whisky and such heavy liquors and in operating on wines and lighter grades of liquors; but in working wines I place the liquor in cl ose casks or receptacles, having the conductors inserted through an aperture in the side, so that the cask can be scaled up .wi'ile the contents are being acted on. For electrodes the metal platcsare bcstadapted for wines; but carbon poles should be used for whisky. The strength ofcurrcnt from the gen orator, in. working wines, should be reduced also to about one-third of that used for heavier liquors say from ten tolii'ieen ccllpowcr. in the course of this operation of the electric cur rent it will be found that the impurities and rattler. separated and thrown out from the body of liquor are deposited upon the surface ol'izhc negative or small plate, and in a short time this surfacebecomos thickly coated or covered with a. slimy or vise-i d substance that rcq'l'lircs to be removed and the surface of the plate or pole kept clean for proper action. This cleansing is accomplished in. a simple and effective manner by simply wrapping or sur rounding the plate with a removable case or cover, E, oi'ielt, canton-flannel, woolen cloth, or other fibrous or textile material that, while not interleriug with the action of the current, will yet protect the plate and constitute a rei ngp ablerecclving and absorbing surface. All the matter a1 id substances or tractcd by the current and precipitated or attracted to and deposited upon this surface, are then readily taken. out by lifting the plate and removing the wrap or cover. This improvement enables the plate to be cleaned without interference with the continuity of the operation, as the wraps or covers are quic cly removed and rc- I00 placed by clean ones. The absorbing character, or quality of the wrapping 18 also of advantage in taking up the extracted matter. I am aware that in the process of aging liquors it has been found that fusel-oils, 820., will gather on one electrode; and I am also aware that in. coating metals by electric deposition one of the electrodes has been covered with a porous iibrous, or textile covering for the purpose of gathering the material; hence Ido not" claim such.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The method of removing fusel-oils or other impurities from alcoholic liquors, which con sists, first, in passing through them an elec tric current by means of wires and electrodes one of which is'provided with a removable en velope or casing; and, secondly, in removing said envelope from the liquor and renewing i1 by putting on another or cleansing and restor ing the old envelope at intervals when it hen received a deposit of impurities, substantialh as hereinset forth.
